HiRISE: Swiss cheese on a red planet
The Martian south polar cap is a layer of carbon dioxide ice, full of pits that make it look like Swiss cheese. The pits form when the Sun heats the ice and makes it sublimate (transform from a solid to … Continue reading

THEMIS: Swiss-cheese weathering in old volcanic region
THEMIS Image of the Day, November 22, 2018. Amphitrites Patera is an old volcanic complex located south of Hellas Planitia. The surface in this VIS image has a unusual “Swiss-cheese” texture, one seen more commonly on the nearby south polar … Continue reading

THEMIS: Swiss cheese and other ice cap textures
THEMIS Image of the Day, October 31, 2018. There are several different surface textures in the South Polar ice. The surface in this image with the round/semi round depressions is informally called Swiss cheese. See more THEMIS Images of the … Continue reading

HiRISE: South residual polar cap monitoring
Spooky — The wonderfully strange landscape of the South Polar region. Beautiful Mars series.
HiRISE: Patterns unique, yet familiar
This close-up image gives the impression of looking like bacterial cells and their internal structures which travel and split in the process of life. These features are fractal in nature: the same image is preserved through different scales, with the … Continue reading

HiRISE: South polar pit or an impact crater?
It is late summer in the Southern hemisphere, so the Sun is low in the sky and subtle topography is accentuated in orbital images. We see many shallow pits in the bright residual cap of carbon dioxide ice (also called … Continue reading

THEMIS: Swiss-cheese terrain on south polar cap
THEMIS Image of the Day, October 4, 2016. This VIS image of the South Polar cap shows several different surface textures. It appears that the circular depressions (which look like swiss cheese) alter with time, appearing to lose the circular … Continue reading

THEMIS: South polar Swiss cheese texture
THEMIS Image of the Day, August 26, 2016. This VIS image of the south polar cap shows a surface with hundreds of circular depressions. This texture is similar in appearance to Swiss cheese. It is caused by solar heating as … Continue reading
